Abstract

A method for controlling pulse arc welding includes repeating provisions of welding currents during a peak rise period, a peak period, a peak fall period, and a base period as one pulse cycle, and performing arc length control based on a welding voltage setting value. The feed speed of the welding wire is set to: a forward-feeding peak value during the peak period; a base period forward-feeding value during the base period to generate a short circuit, where the base period forward-feeding value is smaller than the forward-feeding peak value; and a reverse-feeding peak value when the short circuit occurs. The reverse-feeding peak value is maintained after the short circuit is cleared.
